Application ined my 25, 191s. semi no. 99,911.

o all 'whom it may concern.' Be it known that I, Esens J. R'. BEA'rrnr, citizen of the United States, and resident E the city of Providence, in the county of rovidence and Stute o Rhode Island, have lvented certain new and useful Improve-` further object of this invention is the..

lid'bvision of means on the enga-ging Surface the clamp member for penetrating and bedding itself into the non metallic me to prevent relative movementv of the 'ts after the clamp has been positioned. Vith these and other objects in view, the ention consists of certain novel features construction, as will be more fully debed, and particularly pointed out in the ended claim. n the accompanying drawings: ig'ure 1 is n perspective view showing nir of spectacles having non -metallic frames to which m improved clamp is Nn as being attache i 2*- is a perspective view showing; the )le form of clamp member ns made all in piece. ig. 3H is a perspective view showing the r surface of this chimp as corrugated sversely. i 4 is n view of the clamp member ung the same as being provided with a of spurs adapted to enter the surface of Frame to preventslipping of the parts showing the engaging surface ns corrui. g. 5- is s. modification showing the p member ns being provided with n plu- V of engaging .firms ut cach end.

reine just beyond the end of the clamp member shown in Fig. 6. I

Fi 8- is an edge view of the frame with the ivided clam member secured thereto and arranged to raw the ends of the frame s0 to ether aoout the lens.

eferring to the drawings, 10 designates the frame portion of the eyelass or that portion which encircles and inc oses the lens l1. In forming these frames they are pref- 05 ersbly constructed from a finished rod of celluloid, zylonite or other suitable non-inetallic material. This rod is provided with s. longitudinal groove L?, see Lgs 6 and 7,

and is out of o. length to encircle the lens, 70j

thel abutting -ends 13 must then be provided A with means whereb they may be drawn und fastened together a out the lens.

To aomplish this in a simple end practical wey, have provided a clam or clip 76 15 of metal which 1s formed of a t in elongated body portion I6 having a. pair of laterally extending arms 17 et opposite ends of this body portion, said arms being of a length to be wrapped or folded about the so Aframe. their extremities extending to the lens.

When applyin this clamp to the side of the lens frame w ere the ends abut, I refembly form the body ortion of t e c amp 85 in two parts es best ilustrated i Figs. 1 and 8 and to each of these parts I have atteched one half of a joint member and pass' a. binding screw 20 through both of these-halves, whereby when the sorev` is n withdrawn the frame may beY rung open sufficiently to permit the ready insertion ofv the lens therein, and then by settin up thel screw the frame is bound tightly a out theV lens. Y

These two half joint members 25 may be shaped so that. the usual temple 21 may be pivotnlly mounted between them if desired or when the frame is used Without the temple these joint members 25 may be made only 100 )ust large enough to receive the screw and 'then used exclusively forjoining the ends of the frame together.

l lnsome cases the clamp may be made all in one piece as illustrated in Figs. 2 to 6 105 inclusive when it is desired to attach the bridge member 14 to the inner edge of the immo. see Fig. l. in which cass the body portion 16 othc clip is provided with s 2 1,aea,evi

which the ends of the bridge member are passed and riveted thereby providing a rigid .support for the same.

A featurev of my invention is that the inner surface 22 of the clip is toothed, corrugated or otherwise rougliened,` see Figs. 3 and 4, whereby when applied to the frame with ressure these corrugations embed themseves into theeomparatively soft surface of the frame which effectue-Hy prevents slip inof the parts from the grasp or grip oftecg'p.'

To further insure a positive gripping or clam 'ng action on the frame, I have provide a spur 23, see Fig. 4:, on opposite ends of the clamp which spurs are turned inward 'es illustrated in Fig. 7 so-that when the clamp is applied to the frame it is forced into the relatively soft material and efeotul ally locks" the arts vtogether.

A modiiied orm of clamp or grip is illustrated i'n Fig. 5 in which a pluralit of transverse arms 24 are attached to the ody portion which are wrapped about .the frame.

Having thus described my inventioml de# sire it to be understood that although specific terms are employed, they are used in a generic sense and are not for the purpose of limitation, the scope of the invention -bein defined and limited only by the 'append claim. 4 l

I claim: `v

The Combination with a non-metallic eyeglass frame, of a metal clamp for connecting together the parts of the frame, said clamp comprising a narrow body portion rovided with a. pair of laterally extending endable arms at each end adapted to be wrapped about said frame, the engaging surface of said clamp being grooved laterally to engage the surface of the frame to prevent relative vmovement of the parts when connected thereunto.

In testimony whereof aflix my signature V in presence of a Witness., EARLE J. R. BEATTEY.
